The following describes a unique solution on the Cisco Catalyst Switch to prevent the harm of the worm in a very economical, effective, and scalable way, this greatly saves a lot of company losses.
What makes the administrators of many service operators and Enterprise Networks A headache is not only the constant development and variants, but also the increasing damage caused by attacks. Although worms do not usually destroy any data, the direct and in
Through significant improvements to the software infrastructure, the Cisco IOS software modular Catalyst 6500 maximizes operational efficiency and reduces downtime. By running the modular Cisco IOS subsystem as an independently recoverable process, this innovation can:
Through Fault suppression and stateful process restart, the unplanned downtime can be minimized to improve the availability of integrated applications;
By upgrading ISSU through soft
Spark SQL is one of the newest and most technologically complex components of spark. It supports SQL queries and the new Dataframe API. At the heart of Spark SQL is the Catalyst Optimizer, which uses advanced programming language features, such as Scala's pattern matching and quasiquotes, to build an extensible query optimizer in a novel way. We recently published a paper on Spark SQL, which will appear in Sigmod 2015 (by Davies liu,joseph K Bradley,x
AMD (ATI) today released the 9.6 version of the Linux Catalyst Driver, with two functional improvements: support for the new version of the Linux release version (SLED, SLED 11, RHEL 4.8) and enhanced support for MultiView (Multi-head output technology ). The MultiView feature makes full use of multiple GPUs and allows you to set, manage, and use Multiview configurations. A typical application is to build a multi-screen workstation. As early as 8.8 dr
Preparing the Catalyst 4500 switch for CNAThe switch restores the factory default restore command

Step 1: Download Native IOS software for Catalyst 6509 from CCO Based on the flash card capacity;
Show slot0: shows the flash card capacity. The selected software size should be smaller than or equal to the flash card capacity.
If flash card capacity is 24 M, we choose the IOS software c6sup22-psv-mz.121-8b.E15 for Catalyst 6509, which is used for S2 and MSFC2, feature software for service providers, versio

These switches provide a variety of Fast Ethernet and Gigabit Ethernet line cards, including desktops, branch backbone and servers for enterprise and commercial exchange solution
Fast Ethernet and Gigabit Ethernet line cards
The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide superior combined second-layer switching and intelligent services, which enable network control and sustainability. These switches provide a wide range of Fast Ethernet and Gigabit Ethernet line cards, including the desktop, branch backbone and servers for enterprise and commercial Exchange solutions, and the fiber and cop
The forthcoming release of Ubuntu16.04LTS will discard the private AMD driver fglrx (Catalyst Driver), and developers will encourage the use of open source alternatives to radeon and amdgpu. AMD has been using open-source and closed-source drivers on the Linux platform for the past two years. amdgpu will be used together as a core component by open-source and closed-source drivers. Canonical/Ubuntu developers said that when AMD users upgrade from the
Catalyst Switch Security ConfigurationThe security configuration of the Catalyst switch is to prevent potential network security risks. We recommend that you take the following measures on each cisco device: 1. use enable secret to configure a strong password. Select a password that includes letters, numbers, and special characters. For example: $ PECIAL $ Router (config) # enablesecret $ PECIAL $2. use acl
Ethernet switches are still commonly used. So I studied the comprehensive performance of the Catalyst 2950 remote Ethernet switch. I would like to share with you here, hoping to help you. Cisco's long-distance Ethernet switch can leverage existing copper infrastructure to meet high-bandwidth application requirements. Catalyst 2950 long-distance Ethernet LRE) series Ethernet switches Enable Enterprise and se
AMD's recently released catalyst 10.6 driver package not only brings a lot of new features and game performance improvements to Windows systems, but also changes significantly in Linux systems, for example, the new 2D acceleration architecture is used by default, Red Hat Enterprise Linux 5.5 is officially supported, and OpenGL 4.0/3.3 is officially supported. In particular, the 2D acceleration architecture attracts attention.
In fact, AMD started to
Cisco's flagship Switch replaces the new brain with the new IOS software modularization to bridge the "operational gap" between IT talent and network service needs ".
On April 9, August 29, Cisco Systems announced the launch of a number of software improvements based on Cisco Internet Operating System IOS. These improved IOS software is mainly used in the Catalyst 6500 series switches, Cisco's flagship product. It will help IT managers improve network
According to the definition proposed by IUPAC in 1981, a catalyst is a substance that accelerates the rate of reaction without altering the standard Gibbs free enthalpy of the reaction. This action is called catalysis. A projection involving a catalyst is a catalytic reaction.This substance is not only in chemical reactions, but also in the Internet industry. For example, China today's internet industry can
system, in addition, even when a worm occurs, we need to take measures to minimize its impact and protect our network infrastructure to ensure stable network operation ..
This article describes a unique solution on a Cisco Catalyst Switch to prevent the harm of worms in a very economical, effective, and scalable way.
First, we need to understand the abnormal behavior of the worm and have the means to detect its abnormal behavior as soon as possible.
